Jon Hamm may have a comfy office job while acting on the set of Mad Men, but that doesn't mean there isn't danger lurking around every corner!

During an appearance on The Late Show with David Letterman, the actor recounted all of the injuries he's received by playing Don Draper. Considering the show's stunts mostly consist of drinking scotch, smoking cigars and adultery, it's pretty surprising how seriously he's been hurt!

So far, he's been burdened with a broken hand, eight stitches in his head, and a separated shoulder!

Wow! That all sounds pretty painful.

As office employees ourselves, we understand what he's gone through. We've broken a few nails, endured a few paper cuts, and even sprained our pinky when we hit the "delete" button too hard that one time.

If you ever need to talk Jon, we're here for you. LOLz!
